Now complete the following list:
Minimum value→ 144
Q 1 → 153
Median→ 270
Q 3 → 540
Maximum value→ 629
b. The five-number summary can now be used to construct a box-and-whisker plot for part i. Be sure to provide a
scale on the number line that includes the range from the minimum value to the maximum value.
Minimum value→ 10
Q 1 → 12
Median→ 23
Q 3 → 36
Maximum value→ 58
It is very visible that the right whisker is much longer than the left whisker. This indicates that the distribution is
positively skewed.
